Maybe the great panic of 2013 (or did it start in 2012?) will cause shooters to realize ammo on the shelf is just as important as 15-22's in the rack. I am a bit like the ant who stocks up for unforeseen times and keep a good supply of ammo for every caliber I own. I thought that is what GI ammo cans were made for. Also try ordering .22 from CMP, I did in Jan and a week ago Fedex delivered another 5000 rounds of Golden Eagle Aguila.
I also share .22 with a local for Hunter Safety instructor as the kids sometimes cannot find ammo for the course. I am not able to see the future but do try to prepare for any Zombies lurking on the horizon.
